Using the Engineering DataFor most of the models & sizes we’ve done the calcula-tions for you.
CFM = volume of air flow in cubic feet per minute
Face Velocity = speed of air at the face of diffuser in feet per minute (FPM)
Ak = net area in square feet. This is the lab measured area across the face when air is mechanically forced through the opening.
Free Area (if given) = daylight area (in²) of blade open-ings. Free area is typically only required on natural / gravity movement of air, non-mechanically forced, as in free area needed for combustion air requirements on heating equipment. Use the Ak value (*144 to get to in²) if the free area has not been calculated, but is needed for a given size/model grille requiring free area for combustion.
Equation of Airflow: CFM = Ak (ft²) x Face Velocity (fpm)Example from 421 table above: 100 = .17 x 600 _ num-bers are often rounded
Sizing a SupplyDetermine the amount of CFM (air volume) needed for each supply outlet. This should be done by room heat-ing and cooling load requirements from various design manuals (ACCA Man J, ASHRAE Fundamentals Hndbk) and then followed by the duct design and layout.
Face Velocity - H&C recommends sizing a supply outlet in the range of 500 to 800 fpm face velocity (700 being a common target). The upper end of this range will cre-ate better mixing of room air and longer throws, which is what the typical forced air system is intended to do. However, the Pressure resistance and Noise must be taken into consideration depending upon the applica-
tion. In some instances, greater face velocity is allowed because the pressure and noise can be accommodated.
Pressure Loss (inches of w.c.) – the selection of the face velocity must consider the associated pressure loss that deals with each relative model. An increase in face velocity creates more pressure resistance against the blower’s delivery of air volume. The velocity ranges given previously, in most cases, will have minor effect on the blower’s overall performance given the entire duct system losses that it will encounter.
Noise – an increase in face velocity will create more noise. The tables below show NC design guidelines and also face velocity ranges if NC values have not been tabulated.
Sizing a ReturnAir volume going back to the air handler (fan) must equal what is supplied from the air handler. Therefore the total CFM capacity of the return grilles must equal

If at all possible place the return at an opposite corner of the room.
Room Air Movement• Returns do NOT have much effect on a room’s air movement, regardless of face velocity. They only grab air about a duct diameter away from the face. Most of the room air movement is done by the supplies.
Unlisted Sizes–Engineering DataWhen a size is not listed there are a couple ways to do an engineered estimate. Airflow principles permit you to utilize existing sizes to determine sizes not shown.
Method 1: Use nearest nominal size table entry. If a 14x14 is not given, but a 20x10 is, since the these two
sizes have an approximate equal core area (196 and 200) the table entry for a 20x10 can be used to approxi-mate what the 14x14 grille would perform to.Method 2: A more exact method would be to do inter-polation process between two listed sizes. If 14x14 is not given, but 18x10 and 20x10 are, then this equation will get more exact 14x14 data. Y = Y1 + [{(X - X1) * (Y2-Y1)} / (X2 - X1)] where: Y = unknown CFM or throw that is being computed for 14x14Y1 = CFM or throw of listed 18x10 (for ex 600 cfm)Y2 = CFM or throw of listed 20x10 (for ex 640 cfm)X = 196 in² (nominal area of 14x14)X1 = 180 in² (nominal area of 18x10)X2 = 200 in² (nominal area of 20x10)
Using equation above computes Y = 600 + [{(196 – 180) * (640 – 600)} / (200 – 180)] = 600 + [{16 * 40} / 20] = 600 + 32 = 632 cfm for Y
Method 3: Sizes beyond the table (smaller or larger) can have their CFM or Throw determined by using listed sizes by the following:
CFM for larger sizes:If looking for 24x6 or 24x12 cfm that is not listed, using the listed 12x6 cfm and doubling it or quadrupling it will give the answer for the 24x6 and 24x12, respectively. CFM for smaller sizes:If looking for a 6x6 cfm that is not listed, using the listed 12x6 cfm and halving it will give the answer for a 6x6.
Throw:Double the size and CFM, multiply the throw by 1.5Quadruple the size and CFM, multiply the throw by 2Half the size and CFM, multiply the throw by .67One quarter the size and CFM, multiply the throw by .5
*Pressure loss, face velocity and noise criteria will all remain the same relative to the listed size used to determine the larger or smaller sizes not shown.
Sizing a Return Air volume going back to the air handler (fan) must equal what is supplied from the air
handler. Therefore the total AFM capacity of the return grilles must equal or exceed the
total CFM capacity of all the supply diffusers.
Keeping face velocity low
• Returns should be at 400-600 fpm maximum
• Filter Returns should be at 450 fpm maximum
*ACCA recommends 300 max for filter grilles and 500 max for non-filter grilles.
• The rule of thumb is 2 cfm per square inch of filter size. See table.
• Low velocity reduces noise, especially on stamped face grilles (672/673); fixed-bar
grilles can handle more velocity without noise (94A/96AFB/RH45/RHF45/RCB).
• You really can’t oversize a single point return like you can with a supply. The system
will not be affected adversely, only improved. *This does not apply to multiple return
locations where balancing is more critical to pull in relevant amounts from each room.
• Static pressure is also reduced. Pressure works against & reduces blower delivery
volume (cfm)
• No one expects noise from a return.
Location
• Returns should be put in stagnant air locations that need to be reconditioned.
- High for cooling mode (hot air rises)
- Low for heating mode (cold air falls)
- Both modes, choose a primary season
• Returns should not be near a supply register’s throw range. If at all possible place the
return at an opposite corner of the room.
Room Air Movement • Returns do NOT have much effect on a room’s air movement, regardless of face
velocity. They only grab air about a duct diameter away from the face.

Face Velocity*
*Filter grilles: Tested without filters. Typical capacity is 2 CFM per square inch of nominal filter area. Recommended face velocity is 300-450 FPM. Velocities higher
will decrease filter performance, increase flow resistance, and possibly be of noise concern. Velocity measured 1" from face.

Ceiling or Wall EffectThe tendency of an air stream moving along a wall or ceiling surface to remain in contact with that surface.Core AreaThe total plane area of that portion of a grille, face, or register bounded by a line tangent to the outer opening through which air can pass. The core area is less than the register size. Example, a 14-in. x 8-in. register may have a core that is 1 in. less than the listed size; so, the core area is 13in. x 7in. – 91 sq. in.DiffuserAn outlet discharging supply air in a spreading pattern.DiffusionDistribution of air within a space by an outlet discharg-ing supply air in a spreading pattern.DropThe vertical distance between the base of the outlet and the bottom of the air stream at the end of the hori-zontal throw.Effective Area, Ak (Sq. Ft.)The calculated area of an outlet based on the average measured velocity between the fins.EnvelopeThe outer boundary of an air stream moving at a spe-cific velocity (for example, a 50 fpm envelope).Free AreaThe total minimum area of the openings in the air outlet or inlet through which air can pass.GrilleA louvered covering for an opening through which air passes.InductionThe process of drawing room air into the projected air stream due to the velocity of the projected air stream (sometimes called aspiration).Jet Velocity, Fpm (Face Velocity)The average measured velocity of air passing between the fins.Natural Convection CurrentsAir currents created by a buoyancy effect caused by the difference in temperature between the room air and the air in contact with a warm or cold surface.OutletAny opening through which air is delivered to condition a space.Outlet Velocity, FpmThe average velocity of the supply air, measured as it passes through the plane of the opening in the supply outlet.Pressure Loss, WGIndicates how much total pressure is required to move air through a register.Primary AirThe mixture of supply air from the outlet and room air within the 1 50 fpm envelope.
Radius of Diffusion, Ft.The horizontal distance (throw) from a ceiling diffuser to the point of terminal velocity.RegisterA grille which is equipped with a damper or control valve, and which directs air in a nonspreading jet.ReturnAny opening through which air is removed from a condi-tioned space.Spread, Ft.The maximum width of the total air stream at the point of terminal velocity.Static Pressure, PSThe outward force of air within a duct measured in inches of water.Stratification BoundaryThe boundary between room air currents moving faster than 1 5 fpm and the stratification zone.Stratified ZoneA region in which room air velocity is less than 1 5 fpm.Temperature DifterentialThe temperature difference between the primary and the room air.Temperature Variation (∆T)The temperature difference between points within the same space.Terminal Velocity, FpmWhen the velocity of total air drops to 50 or 75 fpm, depending on the particular application, it reaches ter-minal velocity. Terminal velocity is not sharply defined for all applications.Throw (Blow), Ft.The horizontal distance an air stream travels after leav-ing a horizontal sidewall outlet before maximum velocity is reduced to terminal velocity. For a perimeter outlet, throw is the vertical distance the air stream travels before maximum velocity is reduced to terminal velocity.Total AirThe mixture of projected air and room air set in motion by the supply air.Total Pressure, PtThe sum of the velocity and static pressures measured in inches of water.Vane RatioThe ratio showing depth of vane to minimum width between two adjacent vanes.Velocity Pressure, PvThe forward-moving force of air within a duct measured in inches of water.NC Noise CriteriaA single number noise rating system that indicates what Broad Band, continuous sounds are reasonably accept-able.
